Hey there, this is my first time attempting a regular Atlantic dill pumpkin. The pumpkin is 21 DAP, and the plant is between 80-90 days old. I've been doing a balanced 20-20-20 but I read you should switch to Potash at this point in it's life. I saw potash online is usually a 0-0-50.

Does it make sense to quit the 20-20-20 and just go to the 0-0-50 or do you do a blend of fertilizers? My 21 DAP pumpkin is 18 lbs and not a very fast grower, not yet anyway. Very hot here in NC. Any advice on the switch to Potash is welcome!

One school of thought is that you should keep feeding the plant everything it needs... I think this is the most foolproof route... For example, if you short the plant nitrogen, then the old leaves may senesce sooner? But it probably wouldn't hurt to add more potassium. From the agronomy videos Ive watched arguably, manganese is every bit as important as potassium, similar to how calcium and boron work together.

Google
0-0-50 Water Soluble Plant Food
The only 0-0-50 or similar I had seen that was available
LAST spring was a 50-pound bag that I mistakenly bought as WATER-soluble rather than it was actually 'Soluble' = GRANULAR. It is in my soil now, a year past, lol---I just wanted a huge quantity of it and didn't take even MORE time to choose it as WS, so, be careful as to it being very specifically water-soluble...unless you are tilling it in in the spring as a needed amendment. I, myself would not buy a granular and then 'sprinkle it around' like some labels say can be done. That's just me, lol. I would say to keep after the 20-20-20 as the label says and every other watering or as often as ITS label says, use the 0-0-50, in the recommended dosage, usually 1 TBSP per gallon of H2O. Don't overdo it, as it is better to go ahead slowly + stop than to have to back over what you ran over! Good luck and perhaps give it a day for more responses here, butt u can get to looking for it, anyway - eric g

Wood ash, rock dust, and kelp, and manure, are good sources of potassium. Going the pure chemical route has advantages and disadvantages.

You want to use a fertilizer that is high in potassium, not exclusively potassium. Something like a 15-5-30 that also includes micronutrients.

What barry said. keep using your 20-20-20 and add enough 0-0-50 to make it a total of 20-20-35ish
